SWITCH-OPERATING MECHANISM.

Application filed June 18, 1910.

Specification of Letters Patent.

Patented Apr. 25, 1911.

Serial No. 567,590.

T 0 all whom it may concern:

Be it known that I, RICHARD A. MORRISEY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inSwitch-Operating Mechanism, of which the following is a specification.

My invention relates to improvements in switch operating mechanism, anobject of the invention bein to provide improved mechanism operatec by adevice on the car for moving the switch point to either of its operativepositions.

A further object is to provide an improved rotary member having aplurality of radial arms adapted to be engaged by mechanism on a car formoving the switch point, said rotary member adapted to be turned alwaysin the same direction and operate an improved connecting mechanism so asto throw the switch point from side to side.

A further object is to provide improved mechanism on the car forengaging the IQ- tary member.

Vith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1, is a plan view illustrating myimprove ments, the cover of the boxing being removed. Fig. 2, is a viewin longitudinal section through the boxing and the operating mechanism.Fig. 3, is a view in longitudinal section through the boxing and showingthe mechanism on the car in side elevation. Fig. 4, is a view in crosssection showing the car operating mechanism in end elevation, and Fig.5, is a view in section on the line 5, 5, of Fig. 2.

1, represents the rails of the main track, 2 the rails of the turnout,and 3 the switch point pivoted at 4.

5, represents a boxing or casing which supports at one end, ahorizontally positioned wheel 6, to which a transversely disposed link 7is pivotally connected, and this link 7 projects below the switch point3, and is pivotally connected thereto by means of a Wheel 7, isconnected by a rod 9 with one member 10 of a bell-crank-lever 11, theother member of said lever being given reference character 12 forconvenience of description. Lever 11 is fulcrumed on a pin 13, and isadapted to be moved by my improved rotary member 14, as will hereinafterappear.

The rotary member 14 has a cylindrical body mounted to turn on a crosspin or ournal 15, and is horizontally disposed. The member 14 isprovided at diametrical 0pposite points with pins 16, which are adaptedto engage the members 10 and 12 of the bellcrank-lever 11 when themember 14 is turned. This member 14 is also provided with four radialarms 17, which are located below a slot 18 in the cap plate or cover 19of boxing These arms are adapted to be struck by a lever 20, pivoted atits forward end as shown at 21 to the bottom of the car platform 22.

23, 23, represent links which are pivotally connected to brackets 24depending from the car platform, and said links are pivotally connectedby a bar 25. A spring 26 connects the pivotal connection between therear link 23 and bar 25 with a bracket 27 fixed to a block 28 on thebottom of the car, and this spring 26 normally holds the parts in theposition shown in Fig. 3.

A bracket 29 depends from the platform 23, and a transversely disposedrod 30 pivotally supported in one end in bracket 29, projects through aslot 31 in bar 25, and also projects through a slot 32 in lever 20.

33, is a foot-plunger which projects through the platform 22, and isadapted to be depressed by the motorman when he desires to operate theswitch.

The operation is as follows: If the switch point 3 is in a positionopening the main track and closing the turnout, and the motormanapproaching the switch desires to pass onto the turnout, when his carreaches the proper point he depresses foot-plunger 33. This movement ofthe foot-plunger 33 causes the links 23 and bar 25 to swing downward andforward, which causes rod 30 to swing downward at its free end where itengages lever 20, and the latter will be moved through the slot 18 andwill strike one of the arms 17, and as the car moves along will impartto the rotary member a rotary movement of 90 degrees. This rotarymovement imparted to member 14 will cause one of the pins 16 to engagethe member 10 of bell-crank-lever 11, swing the lever on its fulcrum,move rod'9 forwardly, turn wheel 6 and through the medium of link 7throw the switch point 3 to close the main track and open the turnout.If the next car approaching the switch desires to take the main track, asimilar operation of lever 20 will cause rotary member 14 to turn adistance of 90 degrees, when the pin 16 will engage the lower member 12of hellcrank-lever 11, rod 9 will be drawn rearward, and the switchpoint moved in the opposite direction to that above described. Byproviding two of these pins 16, one is always in position to engage thelever 11, and it will be noted that the rotary member is always turnedin the same direction, and if the switch point is not as desired, theturning of the rotary member by the lever 20 on the car, will move theswitch point to an opposite position.

Various slight changes might be made in the general form and.arrangement of parts described without departing from my invention, andhence I do not limit myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a switch operating mechanism, the combination with a main track, aturnout, and a switch point between them, of a rotary member in advanceof the switch point, means operated by said rotary member for throwingthe switch point, a car, links pivoted at their upper ends to the car, abar connecting said links, a lever pivoted at one end to the car, andbetween its ends having slot and pin connection with said bar, the lowerend of said lever adapted to engage and operate the rotary element,means normally holding said lever elevated, and

| means for depressing the bar to depress the lever, substantially asdescribed.

2. In a switch operating mechanism, the combination with a main track, aturnout, and a switch point between them, of a rotary member in advanceof the switch point, means operated by said rotary member for throwingthe switch point, a car, links pivoted at their upper ends to the car, abar connecting said links, a lever pivoted at one end to the car, andbetween its ends having slot and pin connection with said bar, the lowerend of said lever adapted to engage and operate the rotary element, aspring connecting the rear end of said bar with a fixed point on the carnormally holding the bar and the lever elevated, and means fordepressing the bar and lever, substantially as described.

8. In a switch throwing mechanism, the combination with a main track, aturnout, and a switch point between them, of a boxing located beside thetrack, a rotary member in said boxing having a plurality of radial arms,means operated by said rotary member for throwing the switch point, acar, links pivoted at their upper ends to the car, a bar connecting saidlinks, a spring connecting the rear link with a fixed part of the car, alever pivoted to said car, a bracket depending from the car, a rodpivoted to said bracket and projecting through slots in thefirst-mentioned bar and in said lever, and a foot-plunger connected tosaid first-mentioned bar and projecting through the platform of the car,substantially as described. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
